Google Calendar API - set guest can modify to true

Question

I'm using the google calendar api for a calendar web app. My app allows users to create and modify calendar events and it syncs these changes with user's google calendars. I recently noticed that when one user creates an event and invites another user to that event, that invited user can only change the topic of the event for his/her calendar, not for all the other participants. I would like one user's changes to be reflected on the google calendar's of all the other participants. Google Calendar's website provides an option for allowing guests to modify the event:

but I wasn't able to find where I could specify this option in the google calendar api. How can I use the gcal api to set guestsCanModify to true when an event is created?

Answer 1

That is probably some Google magic in the Google Calendar website. If you check the documentation for Events.insert There is nothing about granting attendees permissions on the event. It would appear that you can only add a user to a calendar but not limit their permissions in anyway with regard to events.

However I think that is a new feature which makes me think it might be something they will be adding to the API in the future. It would be nice if they did.

2021 update: Just set the guestsCanModify to true in Event object https://developers.google.com/calendar/api/v3/reference/events
